if those photos are current i would guess you have more like 2 weeks left. Im seeing lots of white hairs still. harvesting soon your buds wont have a very high thc content and i feel you would be very dissipointed. but if your humidity is high and heat is also high you risk bud rot. air movement will be key to keeping it away. if you are really on edge you could harvest a single plant. which will give you some and allow for more air movement between the rest of them.
